I installed my new system which is comprised of brand new Polk front speakers, a brand new Pioneer head unit, and a brand new Pioneer subwoofer. The only part I didn't buy new was the amp because I had a Kicker KX600.4 amp lying around that I bought about 7 years ago but never installed. It's been kept in a dry place in the original box, so I figured it's basically a new amp.
Anyway, I hooked everything up and it worked great for a few days. I had the 2 front Polks each wired to channels 1 and 2. I wired the 2 OHM DVC Pioneer sub in series (@ 4 OHM) to the amp's channels 3 & 4 bridged. Everything worked great for a few days and then no sound. Initially, I thought it was the head unit. After it was determined the head unit was fine, I tried the amp next.
No fuses were blown, all wires were secure. The power LED was coming on and the amp wasn't in protect mode. I disconnected the RCA cables and hooked up my iPhone directly through it through RCA's and tried playing a song. Still nothing.
I took the cover off and inspected the circuit board, capacitors and nothing seemed damaged or out of order.
Upon closer inspection, I noticed on each side of the amp there were metal tabs that screwed on. Six out of the eight seemed to be have a weird substance on their surfaces, almost like corrosion. This is one of the normal pairs...
Now these are what the corroded ones look like...
What are they and could that be the cause of the amp not producing sound? How would I go about replacing or repairing them?
